* Preserve explicit customizations during canonical library migration
Add bounded runtime, call, and doctest preservation plus explicit remaining-marker metadata. Support mapped legacy test-package migrations without losing ordered guards, and exclude cache directories from both migration paths while retaining canonical assets.
Validation: 53 bounded host-Python tooling tests passed. Tests inspect source and temporary files without executing migrated fixtures. Existing copy-library cache protection is unchanged. No Lib or interpreter changes.

* Integrate migration preservation into existing updater modules
Keep migration orchestration and guarded package moves in cmd_migrate, and marker/doctest metadata in patch_spec. Reuse AST anchor validation and existing test modules, removing all eleven newly introduced helper, test, and data files.
Require caller-selected doctest metadata instead of embedding syntax-case policy. Reject guarded legacy doctests before package writes. Preserve the prior 53 test scenarios and add seven focused metadata regressions; all 60 bounded host tooling tests passed. No Lib, workflow, or native changes.

With CompileOpts::build_list_from_arg set, a list comprehension with one

co_linetable, co_exceptiontable and co_name as objects on PyCode;
build co_code and the varnames/cellvars/freevars tuples lazily in
_co_cached, with co_code deoptimized through deopt_code.
- Move the compiler constant cache (_PyCode_ConstantKey,
const_cache_insert) to builtins/code/const_cache.rs.
- Write every code field with w_object in marshal and pass the read
field objects to MarshalBag::make_code through CodeFields.
- Emit RETURN_GENERATOR/POP_TOP in enter_scope and place SETUP_CLEANUP
after them; drop the generator part of insert_prefix_instructions.
- Add PyCode::first_traceable (_co_firsttraceable) for
_PyFrame_IsIncomplete and sys.monitoring.
- Follow the CPython DISABLE branches in sys.monitoring, the
check_matched signature in warnings, the 3.15 % format error
messages for str and bytes, code_returns_only_none, and the FOR_ITER
stack analysis.
- Compute IMPORT_NAME flags with in_exception_handler.

- Split the | operator into dict_or (_PyDict_Or) and frozendict_or.

- Call through the vectorcall slot in PyCallable::invoke when there
are no keyword arguments, instead of special-casing frozendict.
- Add ensure_builtins (_PyEval_EnsureBuiltins) for eval/exec, and
insert __builtins__ for source strings regardless of globals type.
- Read __warningregistry__ and __name__ from stored globals entries and
accept only None or str for the module name in setup_context.
- Remove the unused PyFrozenDict::from_object.
- Migrate test_dict.py, mapping_tests.py, test_copy.py and
